Bike Rumor Tests the Alloy Hand Drive

Our friends at Bike Rumor got their hands on our ultimate high volume hand pump, the Alloy Hand Drive. With the rise of large, tubeless tires on the scene, it’s no wonder that they wanted to see the best that our high volume pumps have to offer. The Alloy Hand Drive is definitely ready to impress.

“The small pump proved to be invaluable. On our first run, our group experienced a broken derailleur hanger, and four flats. Which turned a quick lap into a painfully slow adventure.During each of those trail mandated breaks, the Lezyne Alloy Drive was called into active duty. While the high volume pump had a tendency to heat up, it did made impressively short work of inflating large volume tires.”

BikeRumor with Another Great Review of Lezyne Product

“It’s become my default pack pump.”

Lezyne’s Pressure Drive mini pump is a CNC aluminum mini pump that claims to go to 120psi. The overlapping barrel and handle with a detachable threaded hose makes for a compact package that easily slides into even the smallest hydration pack. It even does well inside a jersey pocket alongside a tube to keep it from bouncing around or sliding out too easily.

Lezyne claims the oversized barrel reduces the number of strokes required to fill a tire. I didn’t keep count, but getting a tubeless mountain bike tire or cyclocross tire up to riding pressure wasn’t terribly laborious. Filling a road tire wasn’t as much fun, which is sort of a shame because it does fit so well in a jersey and it’s really lightweight. That said, it’s far better than some other compact pumps I’ve used.

Fill up with the details after the break…

The ABS flexible hose threads onto the valve stem and has Presta on one end and Schrader on the other. Because it’s not a fixed part of the pump, you can really put some elbow grease into the pumping without fear of breaking the valve and ruining your ride (or at minimum your tube).

The threaded attachment has a pressure release valve to let air out of the pump hose before removing it to ease the release and keep it from popping off. The downside to threaded attachments is that they tend to pull removable valve cores with them, letting all your hard earned air right back out.

This problem isn’t exclusive to Lezyne. Some of their pumps include adapters to simple press onto the stem, so you could order one of those with your pump. Or you could get a threaded Presta-to-Schrader adapter and use that, but it takes away a little of the magic. And press-on tips aren’t going to stay on as well during vigorous pumping. A better solution is to get tubes or tubeless valves without removable cores, which is what I’m slowly replacing all of mine with.

When you’re done, you simply unthread it, slide it into the other end and thread it in flush:

Even with my large hands, it was comfortable to pump and didn’t heat up too much. Action is smooth and tight, it feels well constructed, and no air leaked out around the valve. It’s become my default pack pump.

The Lezyne Pressure Drive comes in gold (tested), black, red and blue and retails for $44.99.

Lezyne Alloy Dirt Floor Drive Pump Review

Lezyne Alloy Dirt Floor Drive Pump Review

Once again, BikeRumor.com has exposed the newest and greatest features among Lezyne’s product line. He highlighted the ABS Flip Chuck and Slip Chuck and demonstrates how well they work with Lezyne’s Alloy Dirt Floor Drive…..unreal.

Lezyne’s Alloy Dirt Floor Drive pump is a tool with a purpose. That purpose?  Seating and inflating tubeless mountain bike tires.  As anyone who’s tried to get a reluctant tubeless mountain bike tire to seat using a floor pump knows, that job can require a lot of air in a small amount of time- more than most floor pumps can deliver.  While a half-decent excuse is all most guys need to run down to Sears for an air compressor, Lezyne’s big-bore Dirt Floor Drive series of pumps are an appealing alternative.  Hit the jump to find out why…

Lezyne Alloy Dirt Drive Floor Pump Review

In order to provide the air volume that tubeless tire seating requires, Lezyne have increased not only the pump barrel’s bore, but also the hose and internals to minimize air flow restrictions.  In practice, this has allowed me to seat all of the true tubeless and most of the tubeless-ready tires I’ve tried.  Why use a pump when, in my case, there’s a perfectly good air compressor really close by?  In short, because the compressor is awfully noisy in my small workshop and, by the time it’s been switched on and reached pressure I could have used the Dirt Floor Drive to seat the tire.  Besides, nobody likes getting kicked out of bed in the middle of the night to turn off an air compressor they’d left on.

The middle of three Dirt Floor Drive models, the tested $85 Alloy Dirt Floor Drive has a nice wood handle and polished aluminum barrel- a step up from the $75 Classic Dirt Floor Drive’s steel barrel and a step down from the blingtastic $110 CNC Dirt Floor Drive, which has still more machined aluminum hardware and an aluminum handle. For 2012, all three use Lezyne’s presta/Schraeder reversible ABS Flip-Thread Chuck and come with a hose that is long enough to comfortably reach the wheels of bicycles mounted in workstands. The gauge is located at the substantial cast base- not great for legibility, but probably the best choice given its size and heft.  With the large barrel entirely unsuited to road bike use, the gauge only goes up to 70psi, making small pressure differences easy to read.

A big reason that the Lezyne has been so eagerly adopted as part of my workshop is that it’s plain satisfying to use. The polished aluminum makes it look like a serious piece of equipment and the stained wood handle is not only pretty but a pleasure to hold. The height of the pump is just right, allowing average-height adults to manage full strokes without uncomfortable bending- and making shorter pumps feel oddly child-sized by comparison.

Lezyne Alloy Dirt Drive Floor Pump Review<

Back in April’s initial review of the Alloy Dirt Floor Drive pump, I complained about the 2011 Flip-Thread Chuck’s tendency to either thread tubeless valves through their locknut and into the rim and, when removing the chuck, inadvertently removing valve cores (and with them the tire’s contents).  Properly tightening locknuts addresses the first problem and, for 2012, Lezyne’s new Air Bleed System (ABS) chucks address the second.  Now shipping with all Dirt Floor Drive pumps and pictured above, the ABS Flip-Thread Chuck allows the rider to bleed pressure from the pump’s hose after inflation.  This reduces the amount of pressure on the seals and prevents the chuck from unthreading valve cores.  Hooray!

The ABS Flip-Thread Chuck is never going to be the fastest to use (oh! those valuable seconds!), but it makes up for it in simplicity and durability.  The $4 Speed Chuck (pictured below, on the gold Flip Thread Chuck), which is also shipping with new Lezyne pumps, is faster but can be fiddly and leaky in use- so I tend to leave it on the bench.

Lezyne Alloy Dirt Drive Floor Pump Review

At $85, the Alloy Dirt Floor Drive is awfully close to the price of an inexpensive consumer air compressor, which makes it a hard sell on paper.  After working with it for nearly a year, I can speak to its durability- in fact my local shop uses Lezyne pumps on their floor and in their workshop because of the Flip-Thread Chucks’ resistance to sealant fouling.  Unlike an air compressor, the Dirt Floor Drive is  also easy to take to the races- and is miles better than small car-oriented portable air compressors.  When rain means it’s time to switch a 24-hour team’s bikes to mud tires, the Alloy Dirt Floor Drive could almost pay for itself in CO2 cartridges.  Leaving a (nice to have but not essential) tire bleed valve the only thing that I can think to wish for, Lezyne have done a very good job with the updated Alloy Dirt Floor Drive:  it’s a well made tool that does exactly what it’s meant to.  And it looks darn good doing it.
